に折れ疵や変形を発生させろ。The present inventors sequentially stacked titanium alloy thin plates to form a laminate and annealed it, but after annealing, the titanium alloy thin plates are diffusion bonded to each other and are hard to seize and peel off. Also, if the foil is forcibly peeled off, the plate may be bent or deformed, especially if the plate is thin, such as titanium alloy foil.

薄板の界面成分が変るため、好ましくない。A laminate was formed by alternately arranging titanium alloy thin plates and carbon steel. Although the peelability is improved in this case, the titanium alloy absorbs carbon, nitrogen, etc. in the carbon steel during annealing, which changes the interface components of the titanium alloy thin plate, which is not preferable.

い。Stainless steel contains a large amount of chromium, so the carbon and nitrogen contained in it are inactive, forming chromium carbide and bromine nitride, and an inert passive film is formed on the surface of stainless steel. Therefore, even if titanium alloy thin plates and stainless steel are arranged alternately to form a laminate, and this laminate is heated from both sides under pressure to, for example, 830°C for 60 minutes, the titanium alloy thin plates will not be as strong as stainless steel. There is no absorption of carbon, nitrogen, chromium, etc. from the titanium alloy sheet, and the interface components of the titanium alloy sheet do not change.Also, the titanium alloy sheet and stainless steel sheet do not seize after annealing, and therefore the titanium alloy sheet does not peel off. No breakage or deformation will occur.

る。[Effects of the Invention] By carrying out the present invention, it is possible to easily correct a shape defect in a titanium alloy thin plate manufactured by grinding or cold rolling.
本発明の方法では矯正と同時にチタン合金薄板が焼鈍さ
れるために、焼鈍と形状矯正の工程を簡易化できる。In the method of the present invention, since the titanium alloy thin plate is annealed at the same time as straightening, the steps of annealing and shape straightening can be simplified.
